Unfortunately that's not quite possible, rq->lock is really out of bounds. At one point I tried 'fixing' this but there's a whole bunch of nasty that's not going to go away. I've since forgotten most of the details, but aside from logbuf problems there's a whole host of issues with the console drivers themselves as well. If you really want to do this, use early_printk. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
